my problem: My LR 5.x (x64) license (teacher-student-version) is only permanently registered if i run LR in admin mode. Standard mode asks every time for a new license number input. System: Win 7 (x64) + SP 1 + LR 5.6 (x64); PS CC (x64) on the same installation is running in standard mode without any problems.
THX for help
This is because the settings on the standard account are not letting Lightroom save this information to the computer. Lightroom is very different from Photoshop, not just in the jobs they do, but the structure of the application itself as well as how the application licenses itself to the computer. Lightroom requires read and write access to these locations: Preference and other file locations in Lightroom 5
